Optical module board thickness
Recommendation: Ensure hard gold thickness is sufficient (typically >30 micro-inches) for repeated plugging. High Density Interconnection (HDI) products can be used in Optical Module, realizing photo-electric signal conversion. The typical tolerance for this stackup is +/- 7 mil or less, a value that is attainable for most standard materials in PCB stackups. Wear-resistant design: Hard gold plating ensures 10,000 times insertion and removal life. Brightness of an optical module varies as the white point (such as the relative mix of red, green, and blue light that creates white light) is adjusted. For the most accurate measure of performance, brightness should be specified with a target white point.
